One possible version:
To help or not to help
From the passage we know that the writer witnessed a car accident and found no one wanted to help the injured driver, feeling helpless and guilty. As a result, the driver died on the road.
I was greatly shocked by the people?s reaction to this accident. People present there had different attitudes towards it, but they refused to lift a finger even when the injured driver sat up to wave to passing cars. If I had happened to be present at the scene, I would have come to his help and sent him to the nearest hospital or called for help by dialing the telephone number of an emergency center. We might have saved the driver?s life had we helped him without delay.
This accident reminded me of the other day when a woman was seen knocked down by a passing car and one of her legs was bleeding. Just at that time, I called a passer-by for help. I sent the woman to a local clinic with the passer-by at once. At last the woman was saved. She expressed her great gratitude to us for having helped her.
In our life, we should learn to be kind to people in trouble and offer a helping hand to them.
